Oppy hasn't moved much lately and now they are looking at the front right wheel...

Also from the article:
The big science news for Opportunity is that we are now in the etched terrain. This crept up on us slowly, but we're now starting to understand what etched terrain looks like. We've known for a long time that the etched terrain has a "grain" to it, visible in orbital images, that runs north-south. And what we now realize is that the grain is caused by the very large ripples that we've been driving through. These ripples look different from the ones that we saw farther north. The obvious difference is that they're a lot bigger, but that's not all. Look at some of the recent pictures and you'll see what I'm talking about. We're going to look them over pretty carefully as we continue to the south. do we think he is referring to the bright soil that has been appearing in Oppy's tracks of late? or the micro craters? |

Maybe the winds carry the eroded salt grains to the south, and they end up getting deposited on top of the dunes, created the "etched" terrain? -------------------- Space Enthusiast Richard Hendricks
